我们分析的问题，通过时间来选择网站，包括在一个网络的生物保护区的物种保护。如果不能立即对所有地点进行保护，而被排除在外的地点受到开发的威胁，则规划应考虑到地点的预期生物多样性效益和开发风险。我们制定这个问题作为一个随机动态整数规划问题。我们发现，选择的时机是至关重要的，保护预算可提前产生显着更大的生物多样性保护。我们还比较使用最佳和启发式算法的结果。该理论适用于脊椎动物和发展威胁数据从西南部加州。(C)2003 Elsevier B.V.保留所有权利。
We analyze the problem of choosing sites through time to include in a network of biological reserves for species conservation. When sites cannot all be protected immediately, and excluded sites are threatened by development, planning should factor in both expected biodiversity benefits of sites and development risk. We formulate this problem as a stochastic dynamic integer-programming problem. We find that the timing of selections is critical; conservation budgets available up front yield significantly greater biodiversity protection. We also compare results using optimal and heuristic algorithms. The theory is applied to vertebrate and development threat data from southwestern California. (C) 2003 Elsevier B.V.
